'Application filed .Tu1y1 1 1917. Serial No. 179,866.

To all whom it may concern Be it known that I, FREDERICK G. J OHN- son, a citizen of the United States, residing at Jersey Shore, in the county of L'ycoming and State of Pennsylvania, have invented certain new and useful Improvements in.

Machines for Drilling or Boring, of which the following is a specification.

The main object of the invention is the provision of a machine for drilling holes in the webs of steel railroad track rails, especially when the rails are in position upon and sesured to the ties, the machine being adapted ,to be operated by a motorvelocipede engine such as are commonly used on railroads.

However, the machine may be adapted for operation by manual or other than gas engme power, and used fOrOthBr and analo- "gous purposes than that specified. l

' The aceompanyingdrawings illustrate an example of the embodiment of the invention especially adapted for operation by a hydrocarbon engine and for use in drilling holes in the websof steel rails when formingpart ofa railroad track, the same being constructed and the parts combined according to -the-best"mode of procedure I have Figure 1 is a top'plan view;

so far devised forthe purpose.

Fig. 2 is a side view in elevation with certain parts in section. l a i 1 a 'Fig: 3; is a cross sectlon of Fig. 2 at line 33.

Fig.4 is a section of Fig. 2 at line 4-4.

Fig. 5 is a detailed view of and the wheels 2 and 6.

The "supporting and anchoring frame of the machine comprises two cast or wrought one spindle l i metal bars A A, preferabl angular in cross tended far enough to rest upon the topsur- I the ties and the bars in engagement with" section, united by a plurality of rods B, two in this instance.

E located in a plane below the adjacent or central parts of the bars, and an additional bar or metallic connection F is preferably 1 present, and the bar E has ends G G exfaces of two adjacent cross ties of the road bed. The crossbar E should extend for enough to receive a foot of the operator for holding the machine firmly in place upon the rail to be drilled. By this construction Each free end carries a hook C which extends over a rail D, as shown. 1 The opposite ends of the bars are preferably united by an integral curvedbar the gearing is supported above and out of contact with the'roadbed and ballast.

Upon the bars A'A are adjustably supported, so they can be relatively moved, two similar castings H H, each casting being provided with slots I I within which the bars A A are located and adjustably held by set or. stub bolts J, as indicated. Each casting has two holes K K in the same horizontal plane for the passage of the drill shafts or spindles, and each top edge is provided with a casting L removably secured in position by two threaded set bolts M M. Openings N are formed half in the top edgeof each casting and half in the lower part of each casting L within which the two-part power it shaft has its bearings. 1

Upon the inner surface of. each casting and surrounding the openings K K are recesses within which are located the ball bearing plates 0 0 each grooved to receive the balls P and support the gearing.

A sheet metal covering Q incloses the gearing between the end castings and it is removably held in position by threaded stub bolts R, as shown A handle X ma be secured to the end castings by bolts V by whichthe machine can be lifted and carried or moved.

The movable or operative elements are designatedas follows: S S are two shafts or spindles, each being threaded at one end with left handed threads T, ten to the inch, the other end' having a seat for a drillwhich is removably-held by a set-screw U, and a keyway WV extends approximately the entire length of each shaft or spindle.

Upon the spindles are'mounted toothed gear wheels 1, 2, 6 and 7. The wheels 1 and Qhave integral keys 10 which enter the key seats or ways in the spindles so the spindles can be moved lengthwise or slide relative to these two wheels. \Vheels 6 and 7 are interiorly threaded so the spindles can meshes with wheels 6' and-,7, Y The latter part 12 isQprOvided with a disk 16 and ham dle 17 for rotating the disk andwheel 5.

The two parts: 11 and 12 ofthe shaft are united by the ratchet toothed clutch 18, half formed on each of the tW w-heels 3-and5 v so motion can be transmitted from shaft 11 to shaft 12 bythe rotation of the sprocket wheel." The part of theshaft '12" with the wheel 5, disk and handle can'be moved rear.-

wardly to disengage the clutch mechanism (made possible by the open space 19) without disengaging-the teeth of'wheel 5 from the teeth of wheels 6 and 7. 7.

Note that the front or driven gear Wheels 1 and 2 and the feed wheel 5 have thirty two teeth each, and that'the rear or feed wheels 6 and 7 and the wheel 3 have thirty one teeth each. Obviously, by thisarrangement both a the spindles and drills will be rotated by :wheels 3,. 1 and 2-, and at the same time moved'orfed longitudinally by wheels 5, 6

i I and 7 andthrough wheels 1 and 2 as the "5 are slid rearwardly, disengaging the clutch drills penetrate steel rail. I

In using the machine it is placed between the rails and the bars are hooked over arail,

the rear end of the frame being supported upon two tiesr n y By handle 17 the disk, shaft 12 and Wheel 18. Thezdisk is then rotated, whichyturns wheels 5, 6 and '7 andmoves the spindles anddrills-till the drills bear against the web of the rail. J'The sprocket wheel is then ro- "tated through the medium of a sprocket chain uniting the sprocket= wheel with a a similar wheel in gear withqthe shaft ofa gas engine :carriedby a motor ,velocipede located on the track rails adjacent'vtothe I machine. a Y

'When the two holes are drilledin the rail the engine is stopped, the disk, shaft 12=and wheel 5 are slid, rearwardly and rotated,

which action moves the spindles rearwardly .and withdraws the drills fromthe holes in the rail.

Obviously, one hole only can bedrilled removing one of the drills from a spindle.

Further, and when desired, the invention may be embodiedand' used with a single purpose. I have not illustrated the-same by the metal ofthe Web of the 7 the-drawings, inasmuch as such manual ,p

owermeans would be a substantial equiva- 'ent of the gas engine power means deve -ba -v is What I" claim is:

1. The combination of a supporting,

frame; a shaft or spindle threaded at one end and carrying a cutting tool at the 019130:

site end, a driven gearwheel on the spindle suitably supported so as to rotate the spindle but allow longitudinal movement of the f spindle relative thereto; a suitably support- '5 ed second and interiorly threaded feed gear wheelon the threaded part of the spindle;

a powershaft formed in two parts, as 1-1 and- 12,1'1nited by alclutch mechanism each of;

said parts carrying a power gear wheel meshing with the gear wheels on the spindle the part 12 of the power shaft with-its gear wheel being slidable to disengage the clutch mechanism while still in mesh with the feed gear wheel and having meansifor rotating. said part and: gear wheel only to rmove the spindlelongitudinally relative to the driven wheel; andme-ans for receiving energy from; a source of energy and transmitting the same throughtliewtwo power gear wheels tothe said feed and driven wheels independent: of

the spindle; theteeth on said wheels-vary; ing in number so that-the feed gear wheel: will beirotatediat a speed different, from the speed :of theadj acent driven wheel and thus move thespindle' longitudinally through the said 1 driven, .wheele 2.. a The combination of a supporting frame; two shaftsiorvspfindles each threaded at oneend and carrying a cutting tool. atthev opposite end; twodrivengear wheels, one on g i each spindle andfil litablysupported so as-j-to rotate a spindle, butallowlongitudinal-movement of the spindle ,relajt'ive thereto ;;;t-wo
